Docker self hosted version shows control characters instead of colors

[mcallaway]

This is on Mac 10.15.7 with Docker for Mac:

> docker --version
Docker version 20.10.0, build 7287ab3

When using the docker-compose version of cheat.sh:

> git log | head -n1
commit 4d86f0fb959b92e4dfeb141ddd0f6424322d131c

I do:

> docker-compose up --build

Things build without error and start up:

But when I point my browser to localhost:8002 I see:

Yes. Nobody knows what causes it yet. The primary goal was to make it running in Docker.

I believe it works now

I am facing this same issue now.

> docker --version
Docker version 20.10.10, build b485636f4b

[abitrolly]

So far I traced it to

cheat.sh/lib/frontend/html.py

Line 36 in 609c790

Found the problem. Apline by default comes with limited BusyBox version of sed which doesn't process ansi2html rules correctly.

I submitted a patch pixelb/scripts#30 to warn about it.

Testing a fix now.

[abitrolly]

@mcallaway @aamehedi this is now fixed.

[aamehedi]

@abitrolly Thanks a lot. It works!
